Hardware teardown of the dual-68000 DSP accelerator board used in the Stardust project.

CPU #0 handles host bus interfacing and DMA, while CPU #1 is dedicated entirely to a 16-bit MAC (multiply-accumulate) unit.
The board features two 68000 CPUs clocked at 12 MHz sharing a dual-ported 128KB static RAM bank.

Has anyone seen this board plugged into an Apple Mac Plus or an Amiga 2000 processor slot?

Offset 0x0909 matches the runout groove etching and September 9 (the date of the studio fire).
